To all whom it may concern Be it known that 1, MAX QUAAS, a citizenofthe United States, residing in the city ofv This invention relates tomachines'. for

making tubes suitabie for the bodies. of paper containers by Winding andapplying an'adhesive to blanks and setting the adhe- Y sive and thelaminations of the tubes. 1t:

comprises automatic means whereby blanlrs are rendered adhesive, Woundon a longitudinally niovable and revoluble mandrel in sueessivetraveling holders, and the tubes delivered from the holders tosuccessive setting devices traveling in proximity to drying mechanism.

The primary objeot is to provide an ini nroved automatic rnaohine whichwill perrorni eoiently and rapidly in synchronous relation the severaioperations required or setting tubes.

The characteristio features of the improvents are nliy dis-Closed in theoiiowing ion and the accompanying drawings ation thereof.

i 'on of the saine;

evation opposite 4 is broken bro'vm seotionai the clutch 4, operated bymeans of the parts 4', 4 and-4', the shaft having the pinion 5 fixedthereon. A shaft 6, journaled in the frame, has fixed thereon a spurWheel 7, which is engaged by the pinion 5, a drum 8 containing the canigroove 9, and the Wheel 10 provided with a segmental cylindrical iange11 land a lug 12 having a pin 13 there- "on disposed eqi-iidlstant fromthe ends of the ange. The Wheel 10 engages and operates a sta-r Wheel14, revoluble on the shaft 2 and having the concave segments 15 Withinwhich the ange 11 revolves sequentially as the Wheel 14 vis given a stepby step movenient through the engagement of the pin 13 in itsradialslots 16. A spur Wheel 17, fixed to and revolved intermittently by theWheel 14, engages the spur Wheel 18 which is fixed to the spur Wheel 19,the latter Wheels being I loosely journaled on the shaft 6. A shaft 20,revoluble and longitudinallynnovable the frame, has splined thereon apinion 21 engaged by the spur Wheel 19 and ined to a pinion 22. An idlerpinion 23, g'onrnaled by means of the shaft 24, is engaged by the pinion22 and has fixed thereto a pinion 25. A shaft 26, journaled inthe frame,has a spur Wheel 2? fixed thereon which is e gaged by the spur Wheel 25.rihe pniiey acts, through the deseribed inter i parte, to rev-@ive thedrum 8 oonstant. ,.T eno. the shafts and 26 intern entiy.

The drinn 8 engages, i

sleeves tothrust the latter in opposite directions. A short shaft 40 isset in a socket 20 in the forward end of the shaft 20, the shaft 40having a pin 41 therein which engages a slot 42 in the shaft 2O wherebyrelative longitudinal movement is prevented and a limited relativerotary movement is permitted. A pin 43 extends through the hub 44 of theshaft 40, passes freely through square holes 45 in the sleeve 36 andprojects into diagonal cam slots 46 in the sleeve 32: the cam slots,holes and pin permitting the shaft 40 to turn relatively to the sleeves32 and 36 and providing for the longitudinal movement of the sleeve 32relatively to the sleeve 36. A conical mandrel body 47 is fixed to theshaft 40 by its sleeve 48 on the shaft and a pin 49 passing therethroughinto the circular slots 50 in the sleeve 36. A conical mandrel sleeve 51is fixed tothe sleeve 36 and turns on the body 47, the latter having alongitudinal flange or lip 52 which is adapted to vrock in thelongitudinal slot 53 of the mandrel sleeve to engage and disengage theedges of blanks 54 to be wound onv the mandrel.

, As the drum 8 revolves, the cam groove 9, through its engagement withthe roller 28 on the slide 29, causes the latter, through its engagementwith the collar 30 and spring 31, to reciprocate the shaft 20 'and thesleeve 32 with its connections, the form of the cam groove 9 being ofsuch character as to hold the shaft against longitudinal movement in itsforward position, with the mandrel hub 51 in the bearing 51, for adesired period.' When, in the forward movement'of the shaft 20,; theange 32 on the sleeve 32 engages the bushing 33, the sleeve is heldagainst further longitudinal movement, and the further longitudinalmovement of the shaft 20 causes the short shaft 40 and the mandrel body47, with the sleeve 48 thereon, to turn in the'respective sleeves 36, 32and 51 through the engagement of the pin 43 with the cam slots 46, theflange 52 being thereby rocked in the slot 53 to engage the edge of ablank 54. When the revolving drum 8 retraots the shaft 20, through theintermediate mechanism, the pin 43 and cam slots 46 cause the shaft 40and mandrel body 47 to turn in the opposite direction, thus retractingthe flange 52 and yreleasing the tube wound on the mandrel. It will beunderstood thatthe relative longitudinal movement of the sleeves 32 and36, permitted by the aperltures 38 and 45, subject to the action of thespring 39, provides for a desired flexibility The winding of the blanksupon the mandrel is eected in the yforward position of the latter withinthe conical holders 55 carried by a wheel 56 which is revoluble on theshaft 6.' The holders contain the respective longitudinal slots 55 whichare successively positioned adjacent to the inner edge and.approximately in the plane of the table 57 from which the blanks are fedto the mandrel disposed in a positioned holder. When a blank is engagedby the mandrel and is being wound thereon, a segmental conical roller58, Whose periphery revolves in the aperture 57 of the table, engagesthe inner surface of the section of the blank which forms the laminationor laminations succeeding the rst lamination of the tube 54 and appliesan adhesive thereto, a roller 58 pressing the blank against the segmentin the aperture 57 The segment 58 is revolved by the shaft 26 which actsthrough the shafts 59 and 60 connected by gimbal joints 61 and 62, asthe segments lshaft 60 is journaled in the paste reservoir 63vat anangle to the shaft 26. The adhesive -is applied to they segment by theroller 64 fixed on the shaft 65 which is journaled in the pastereservoir; a doctor roller 66, on the shaft 67 journaled in thereservoir, and a scraper 68', acting in contact with the segmentalroller to regulate the amount ofpaste thereon. The several paste rollersare revolved together through the action of the spur wheel 68 on theshaft 60, which engages the pinions 69 and 70 on the respectiveshafts 65and 67.

The mandrel is 4inserted in a holder with the slot 53 in registrationwith the slot 55', the blank 54 is inserted through the slot 55 into theslot 53, the lip 52 is turned to engage the blank, the mandrel isrevolved, the contact with the blank, and the.roller 58 (lifted bya yoke60 movable in' guides 58a by a cam 60 on the shaft 60) descends` topress the blank in contact with the seggumming segment '58 is turnedinto' 'permit the passage of a second blank, andl a cam 58b on thesegment engages a roller 58 on a lever 58 having a fulcrum 58 andelevates a bridge 58' which supports the blank. When no blanks are beingfed tothe machine, the roller 58 may be manually elevated and held outof contact with the gumming segment bv means of a lever. 60a fulcrumedonl a bearing 60c and connected by a link 60b with the cam 60s looselyjournaled on the shaft 60 and engaging the yoke 60". When the -operationof winding a blank upon the mandrel within a holder has been completedand the mandrel Withdraw'n from the holder, the holder Wheel 56 isrevolved by the shaft 6 through the wheel 71 (having the segmentalflange 72 and the lug 73 with the pin 74 thereon.) i which coperate withthe star wheel 7 5` (having the concave segments 76`in which the flangeis adapted to revolve sequeny Aannuals the frame) on which theY wheel isfixed and having the pinion 79 fixed thereon and an .internally toothedring 80 fixed to the wheel 56 and engaged by the pinion 79.

The intermittently `moving wheel 56 carries the holders 55, with theconica-l tubes 54 therein, to a position opposite a knocker orl plunger81 which strikes the tubes and disengages themv from the holders, thedisengaged ltubes being Vseated on the conical `forms 82 of the seamsetting mechanism by a rocker arm 84 fulcrumed on the bearing 85v andacting in the slot 55. The plunger 81 is loperated by a stem 86 whichreciprocates in a cylinder 87. The plunger is moved toward the holder bya spring 88 engaging the rear end of the cylinder and a collar l89 onthe stem, and is withdrawn by the `engagement of its cam 90 with a cam91 fixed on a revoluble shaft 92, the latter having a sprocket wheel 93fixed thereon and driven by a chain 94`which passes over a sprocketWheel 95 fixed on vthe shaft 6. The arm 84 is oscillated by a link 96and a lever 97 adapted to rock on the Vfulcrum 98 and having the roller99. A' cam 100 on the shaft 6 enga es the roller and moves the lever inone irection and a lever 101, having a fulcrum 102 and provided withthey weight 103, is connected with the lever 97 to move it in the otherdirection. Auxiliary means-for removing any tube that may stick in aholder are provided by a lever 129 rocked on its ulcrum131 by a pin 130on the slide 29; a link 132 connecting the lever 129 with a rod 133movable longitudinally in the bearings134; and a finger 135 on the rod133 and movable rthereby through the slots 55 of the holders when thelatter are in a stationary position in the lower part of their course.

Conical seats or forms 82 arev fixed to stems 104 by bearings 105,- thestems are fixed to knuckles 106 adapted to rock in bearings 107, sleeves108 (provided with bearings 109 and 110) are movable longitudinally onthe stems 10i, springs 108' are disposed on the 'stems and sleevesbetween the bearings and 109, crank levers 111 have the ulcrums 112 ontheknuckles 106,.

pintles 113 connect the crank arms 111 having the cams 111a with thebearings 110 and pintles lli'connect the crank arms 111 with the shoes115, the latter conforming to and pressing the sections `of the tubescontaining the seams against the forms or rocking seats 82. 'Thebearings 107 are fixed to cleats 116 which are secured to sprocketVchains 117 carried by sprocket wheels 118 and 119 fixed on thcrespective shafts 120 and 121 journaled in the frame; this mechan'smbeing revolved by a sprocket wheel 122 fixed on the shaft 120, asprocket wheel 123 fixed on the shaft 6 and a sprocket chain 124. As thelink belt, formed by the cleats 116 and chains 117, moves the seamsetting devices around the wheels 118 and 119, the wheel 56 moves in theopposite direction so that the respective holders 55 and forms 82 arebrought into registration. A stationary cam 125 engages the cam 111a ofthe registering form, rocks they crank lever 111 and draws back thecorresponding shoe against the action ofthe spring 108, while the parts81 and 84 are operated to transfer the tube 54 from the holder to theform, whereupon the setting device whichv receives the tube isadvanced-so that the cam 1113 passes the cam and the spring 108 .rocksthe crank lever l111 and presses the shoe 115 against the tube on theform, the pressure being maintained while the tubes are being carried inproximity' to the heat- `ing coils 126V located beneath the belt.

the settingy devices (which are turned by gravity in their bearings 107toa position transverse to the belt in the lower part of their course)are carried around the wheels 119, a stationary cam 127 engages the cam111, rocks the vlevers 111 and withdraws the shoes 115 from the tubes 54which are thus permitted to fall from the forms 82. As the seam settingdevices rise following the delivery of the tubes therefrom, they arebrought to the horizontal position by the engagement of the knuckles 106with a cam 128 xed on the frame.

It willbe understood that the several operations are timed so that themandrel moves forward into a. registering holder of the stationaryholder wheel, engages ablank which is/passed thereto from the feedingtable through the slot in the Aholder, and winds the blank within theholder while the pasting apparatus applies the adhesive y thereto.
